Fort Lauderdale, Fla. — A group of 33 wounded evacuees from Haiti arrived in Broward County, accompanied by former U.S. presidential candidate John Edwards.

A C-130 carrying the group arrived Saturday morning at Fort Lauderdale-Hollywood International Airport. The Broward Sheriff's Office reports 15 of the passengers were critically injured.

Edwards, a former senator from North Carolina, has been in Haiti helping with humanitarian efforts and rode with a child taken to Broward General Medical Center for treatment. Others were taken to various hospitals in Broward and Miami-Dade counties.

The sheriff's office reports that planes with wounded evacuees have been arriving for the past week. Another seven injured people, including two children, arrived Sunday morning.

Edwards arrived in Haiti Thursday, the same day he issued a statement acknowledging for the first time that he is the father of the nearly 2-year-old daughter of his ex-mistress, Rielle Hunter.

He traveled with a group of doctors and planned to deliver medical supplies and aid such as food and generators. He also planned to review schools he had been involved with in the past and see what help they needed.

"I was in Haiti about a year ago and was really touched by the people here and what they were going through," Edwards told CBS News. "When the earthquake hit, I saw these images that you guys brought back to America. And it was heartbreaking, absolutely heartbreaking. So we started organizing, trying to figure out what we could do here."
